NUT.

Specification of Letters Patent.

Application filed March 14, 1921. Serial No. 452,382.-

To all whom it may concern.

Be it known that ALEXANDER MoKiM, deceased, late a citizen of the United States, did invent certain new and useful Improvements in Nuts, of which the following is a specification, referencebeing had 'to the accompanying drawings.

This invention relates to certain improvements in nuts and has relation more particularly to a device of this general character of a threadless type, and it is an object of the invention to provide'a device of this general character with novel and improved means whereby the same may be readily and effectively applied to a coacting bolt or other work.

Another object of the invention is to provide a novel and improved device of this general character embodying a split ring adapted to surround a bolt or other work, together with means whereby said ring is caused to effectively clamp the bolt or the like, whereby the device in its entirety is maintained in desired applied position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of the improved nut whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that the invention may be the better understood, the same will be described with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation with portions broken away of a nut constructed in accordance with an embodiment of the invention;

Fig. 2 is a view in elevation of the outer end odf the structure as illustratedtin Fig. 1; an

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1..

As disclosed in the accompanyin drawings, S denotes an elongated sleeve or collar split longitudinally, as at 1, so that said sleeve or collar may be readily expanded or contracted in accordance with the requirements of practice. Extending outwardly from the sleeve or collar S at a point in relatively close proximity to an end thereof is a lug 2, the outer face 3 of which is downwardly and outwardly inclined, and said face is provided at a desired point with a recess or pocket 4 for a purpose to be hereinafter referred to. The lug 2 is disposed preferably at an angle of substantially ninety degrees with respect to the split 1.

The portion of the sleeve or collar S at a point substantially diametrically opposed to the lug 2 is provided therealong with an outstanding rib or flange 5 and the opposite end portions of said rib or flange 5 are provided with the outstanding lugs or ex tensions 6 and 7. The outer faces of said lugs 6 and 7 are inclined in the same general direction as the inclined face 3 of the lug 2 with said outer inclined faces of the lugs or extensions 6 and 7 substantially coplanar.

The outer faces of the lugs orextensions 6 and 7 are provided therealong with the grooves or channels 8 substantially V-shaped in cross section and which grooves or chan nels are adapted to receive the opposite end portions of a rod 9 possessing a certain degree of inherent resiliency and preferably steel. This rod 9 is preferably V-shaped in cross section and the apex portion of its extremities are adapted to seat within the grooves or channels 8. It is to be noted that the side walls of the rod 9 are arranged on a lesser angle than the side walls of the grooves or channels 8.

L denotes an elongated rigid loop member through which the sleeve or collar S is directed and through which is also disposed the rod 9. One end portion of the loop L has threaded therethrough a screw 10 provided at its outer end portion with the wing 11 to facilitate its desired rotation. The opposite or inner end portion of the screw 10 is tapered, or otherwise reduced, as at 12, to seat within the recess or pocket 4 hereinbefore referred to.

The opposite end portion of the loop L is providedwith the transversely spaced cam portions 14 disposed inwardly in a transverse direction of the loop L and which cam portions 14, upon requisite rotation of the screw 10, contact with the side marginal portions of the rod 9, whereby the loop L Patented Oct. 18, 1921.

, enlarged to provide the blocks 15 and said blocks are provided with the outstanding pins 16 disposed through the longitudinally directed slots 17 provided in the side mem bers 18 of the loop L. The slots 17 are of sufiicient length to permit the desired endwise movement of the loop member L while the coacting pins 16 serve to maintain the loop member L against separation or displacgment with respect to the sleeve or collar From the foregoing description it is thought to be obvious that a nut constructed in accordance with this invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and itv will also be obvious that the invention is susceptible of some change and modification without departing from I the principles and spirit thereof and for this reason the invention is not limited to the precise arrangement and combination of parts herein shown in carrying out the invention in practice except a hereinafter claimed. 7

What is claimed is:

1. A device of the class'described comprising a loop member, a split sleeve disposed through the loop member, longitudinally spaced lugs carried by the sleeve, a rod disposed through the loop member and contacting with the lugs, and a member threaded through the loop member and engaging the sleeve at a point remote from the lugs.

2. A device of the class described comprising a loop member, a split sleeve disposed through the loop member, longitudinally spaced lugscarried by the sleeve, a rod disposed through the loop member and contacting with the lugs, a member threaded through the loop member and engaging the sleeve at a point remote from the lugs, and reacting meanscarried by the Sleeve and loop member whereby said sleeve and loop A deviceof t member are held one to the other for relative through the loop, member, longitudinally spaced lugs carried by the sleeve, a rod disposed through the loop member and contacting with the lugs, and a member threaded through the loop. member. and engaging the sleeve at a point remote from the lugs, said rod being resilient. V r i 4.

5. A device of the class described comprising a loop member, a split sleeve disposedthrough the loop member, longitudinally spaced lugs carried by the sleeve, a rod disposed through the loop member and contacting with the lugs, and a member threaded through the loop member and engaging the sleeve at a point remote from the lugs, said lugs being provided with grooves in which the end portions of the rod are received, said grooves and the coacting portionsof the rod being substantially V-shaped in cross section.

' 6. A device otthe class described com prising a loop member, a split sleeve disposed through the loop member, longitudinally spaced lugs carried by the sleeve, a rod disposed through the loop member and contacting with the lugs, and a member threaded through the loop member and engaging the sleeve at a point remote from the lugs, said lugs being provided with grooves in which the endportions ofthe rod are received, said grooves and the coacting portions of the rod being substantially V-shaped incross section, the angular portion of the side walls of-the rod being less than that of the side walls of the grooves. 1

7. A device of the character described comprising alongitudinally split sleeve, an outstanding lug carried by the sleeve and positioned at an angle of substantially ninety degrees with respect to the split of the sleeve, oppositely directed lugs carried by the sleeve and spaced longitudinally of the sleeve, .a rigid loop member through which the sleeve is directed, a rod disposed through the loop member and contacting with the outer ends ofthe second named lugs, and a member threaded through the loop memberv for contact with the first named lug whereby rotation of said last named memberin one direction moves the loop member in a: direction to engage therod and to contract the sleeve.
